Roads under construction

Weather permitting, several streets are scheduled to be under construction as part of the City’s 2019 Local Street Rehabilitation Project. Construction is slated to begin Sept. 9 on the southern part of Morgan Blvd. and the southern part of Morgan Circle. Nagle Paving Company of Novi, is the contractor;  the City of Northville’s Public Works Department (DPW) and staff from the City’s engineering consultants overseeing the work.

Work will include: the milling of the concrete roadway and replacement with 2” of asphalt, full depth removal and replacement where needed, removal and replacement of some sidewalk ramps and driveway approaches, and areas of minor curb replacement along the stated sections of Morgan Circle and Morgan Blvd, and Morgan Court. For residents and visitors, two-way traffic will always be maintained on Morgan Boulevard and Larry Drive. 

The contractor is anticipated to conduct activities between  7 a.m.. to 8 p.m., Monday - Friday. Work is currently not scheduled for Sundays or holidays. 

During construction activities, on-street parking will not be permitted. If construction will affect access to your driveway, you will be notified no less than 24 hours in advance. 

If you have any questions or require special accommodations, please contact the City’s engineering consultants, Fleis & VandenBrink’s onsite representative at 586-899-7015 or their office at 248-536-1997. The consultants have also set up a website portal that provides maps and road construction updates and allows residents to post questions and comments. 

We understand construction may interfere with residents' daily activities, and we will do our best to ensure as little down time and inconvenience as possible. We appreciate your cooperation and patience during these street construction projects.

Street construction work to begin soon

Nagle Paving Co., of Novi, was approved as the contractor to repair and replace streets during the 2019 construction season at a cost of $1,031,473. This summer and fall, work will commence at Lexington Court and Glenhill Drive (mill & fill), Morgan Blvd. (reconstruction), Cady Street (reconstruction of 250’ and addition of eight parking spaces), Morgan Circle, Morgan Court, MacDonald Drive, Taft Road and Baseline Road (mill & fill). In total, the work spans 1.7 miles of pavement.

Residents on those streets will be notified about work schedules, detours and parking restrictions. Updates will be reported on the City's website and social media (Facebook and Twitter). 

The City had to look for alternate solutions after no bids were received for the City’s 2019 Local Road Reconstruction and Rehabilitation Program. DPW director Loyd Cureton said Northville wasn’t alone in not getting responses to their request for bids. Other local municipalities also came up empty-handed. “This was due to several factors, including significant existing workloads, rain delays, the loss of key personal, and difficulty finding subcontractors,” Cureton said.

“In June, the City requested a meeting with Nagle to discuss what work might be accomplished yet this season if the scope of work was modified and we allowed an alternate schedule,” he added.

The City’s engineering consultant, Fleis & VandenBrink, reviewed and recommended the City proceed with Nagle, after the company provided a quote. The consultant noted the unit prices provided and total cost proposed were consistent with recent bidding seen throughout the region. Nagle has an extensive background in asphalt paving and road rehabilitation and reconstruction projects throughout metro Detroit. They have completed many projects successfully in the City of Northville.

City Council approved entering into the contact with Nagle at the July 1 City Council meeting.

The remaining work originally planned for the summer of 2019 – Allen Drive, Stanstead Road, Potomac and Rogers Street – will be rebid in November, with work expected to be completed in this budget year.

Keeping you informed 

Road construction in 2019 will get under way soon.

The bond issue that voters approved in November 2018 enables the City to significantly improve the condition of streets in the community more quicker than if the bond had not passed. However, it will take time to bring all streets up to a good standard. 

For some history on the planning that went into the bond, watch the Mayor’s bond presentation.

What is the street millage costing you?

Property owners in Northville can assess their cost for the street bond by using the online calculator. You can find your taxable value on your summer 2018 tax statement or by looking up your property here: property tax and assessing lookup. The taxable value is no more than half of the market value. The calculator multiplies your taxable value by 0.00098.

City of Northville has a plan to prioritize road repair and replacement

There’s a science to determining how roads should be repaired or replaced, balanced by practicality and traffic flow.

The process of evaluation and analysis starts with rating roads using the Pavement Surface Evaluation and Rating (PASER) system, an industry-standard assessment in which trained analysts drive each segment of road (from intersection to intersection) and score it from one (the worst) to 10 (a new road). Roads rated 7 or 8 may require routine maintenance, such as crack sealing or minor patching. Roads rated 4-6 are considered to be in “fair” condition and may need preventive maintenance, such as an overlay or joint repairs. Roads rated less than 4 are candidates for extensive repairs or reconstruction.

After each segment is rated, Roadsoft, a pavement management software, is used to define the type of repair, its cost and the allocated budget, to determine the most cost-effective way to attain the best overall condition for the roadway network (roads owned by the City). The software also defines how many lane miles of each type of repair must be done to attain the long-term condition goals for the roadway network. The City aims to attain an average rating of 6 OCI (Overall Condition Index) with millage funding.

To determine which roads are the best candidates for the extensive repairs, a Network Priority Rating (NPR) is calculated for each pavement segment. Calculations are based on these five factors: PASER rating, pavement priority, pavement use, segment length, and pavement classification.

Pavement Priority is classified as: 1) low – only residential and mostly local residents; 2) medium – periodic commercial, frequent residential traffic; and 3) high – frequent commercial and high use of local traffic.

Pavement use has four categories: major residential, major commercial and local residential and local commercial. It is related to the location, degree of utilization and expected traffic type/frequency of a particular road segment.

Pavement classification – There are basically five categories: 1) asphalt standard duty, 2) asphalt heavy duty, 3) concrete standard duty, 4) concrete heavy duty, and 5) asphalt overlay composite (asphalt over concrete). Standard vs. heavy-duty is based in part on the thickness of the pavement.

Once the NPR is calculated, all segments that are candidates for a particular treatment are determined, based on pavement type (asphalt, concrete, or composite) and PASER rating. These segments are then evaluated using NPR to determine a rating, with the highest values given top priority. Segments are then chosen for repair until reaching the total lane miles of treatment recommended in a particular year.

For example, this shows one year of the City’s long-term strategy:

Type of road Repair Lane miles

 Asphalt Reconstruction   .252  
 Asphalt 3” Mill and Overlay   .256  
 Asphalt Crack Seal   4.062  
 Composite 3” Mill and Overlay
 Composite Crack Seal
 Concrete Asphalt Overlay   .330  

Types of repairs that will improve the road network

Upgrades to roads include reconstruction, mill and overlay, and crack seal repairs for roads made of asphalt, composite and concrete. Reconstruction is a complete tear-down and rebuild; mill and overlay is a process of grinding down the top layer – the wearing layer – and setting down new layers of material (allowing the base of the road to last longer); and crack-seal repairs are used to apply asphalt to a crack to prevent water from seeping into the pavement and potentially creating a pothole.

When scheduling repairs or replacement, practical aspects must be taken into account. For example, when major water main or sewer work is scheduled in a given year, major road repairs on that same section of road would be made immediately following that repair.

Once all streets to be repaired are determined for each year, a manual review is conducted to balance the location of repairs with other construction planned or underway (e.g. construction of new homes or a commercial building). That way, repairs don’t create gridlock in one part of town. With proper planning, multiple repairs can be done sequentially.
